Abstract: The development of Grid environments over recent years now allows scientists access to a range of shared resources which may be located across different sites. These include computational resources such as large parallel computers which may be used to produce accurate numerical simulations in a relatively short time. Since different computer architectures have different performance characteristics and different levels of availability, to be able to make optimal decisions concerning their selection and utilization for a given scientific application, we need to be able to predict the application's performance on each available parallel environment. In this research we seek to model the performance of typical state-of-the-art numerical software, based upon multigrid techniques, on different distributed memory parallel machines for varying numbers of available CPUs. The goal of the work is to use these models to support decisions as to which resources should be requested or reserved.
